The need of cooling devices that are lightweight, low powered, physically flexible, easily manufactured and most importantly exhibit high heat transfer rates are requirements that space agencies demand in a cooling system. Therefore, Pulsating Heat Pipes (PHPs) are being extensively investigated to provide these requirements. This paper summarizes the current development of cryogenic Pulsating...
The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) will increase the accelerator’s luminosity by a factor 10 beyond its original design value, giving rise to more intense collisions and generating an intense flow of debris as a consequence. A new design of the beam screen for the inner triplets, incorporating tungsten alloy blocks, has been developed to shield the...
As applications of superconducting logic technologies continue to grow, the need for efficient and reliable cryogenic packaging becomes crucial to development and testing. A trade study of materials was done to develop a practical understanding of the properties of interface materials around 4 K. While literature exists for varying interface tests, discrepancies are found in the reported...
The work detailed here describes how a novel approach has been applied to overcome the challenging task of cryo cooling first crystals of many of the world’s Synchrotrons’ more challenging beam lines. The beam line configuration investigated in this work typically requires the crystal to diffract 15 Watts of 8.27x10-11m wavelength X rays and dissipate the additional 485 watts of redundant X...
Abstract:
Cryocoolers have been widely used for cooling down the superconductors, cells, cryogenic liquid storage tanks, etc. Since they can only operate vertically, and provide cooling at cold heads, it is difficult to be utilized in distributed cooling and long-distance systems. It can be achieved by a more flexible and high-efficiency heat transfer method connecting cryocoolers and objects....
